A random sample of n = 900 observations from a binomial population produced x = 655 successes


A random sample of n = 900 observations from a binomial population produced x = 655 successes. Estimate the population proportion p and calculate the margin of error. (Please note, your estimate is a point estimate, and the margin of error is 1.96 x S.E.)
